Insights

PARP inhibitors offer precision medicine for BRCA-deficient cancers, but resistance necessitates new DNA repair targeted therapies. Research is exploring additional synthetic lethality strategies for improved cancer treatment.

Area of Science:

  • Oncology
  • Genetics
  • Pharmacology

Background:

  • DNA repair mechanisms are crucial for cancer cell survival.
  • Targeting DNA repair pathways represents a promising precision medicine strategy.
  • Poly (ADP-ribose) polymerase (PARP) inhibitors have shown efficacy in specific cancer types.

Purpose of the Study:

  • To review the clinical status of PARP inhibitors in cancer treatment.
  • To discuss emerging DNA repair targeted therapeutics.
  • To highlight the ongoing search for novel synthetic lethality approaches.

Main Methods:

  • Literature review of clinical trials and translational research.
  • Analysis of the clinical utility and resistance mechanisms of PARP inhibitors.
  • Overview of other DNA repair targets in clinical development.

Main Results:

  • PARP inhibitors have transformed treatment for BRCA-mutated breast and ovarian cancers.
  • Intrinsic and acquired resistance limits PARP inhibitor effectiveness in some patients.
  • ATM, ATR, and WEE1 inhibitors are among other DNA repair targets under investigation.

Conclusions:

  • While PARP inhibitors are effective, overcoming resistance is key.
  • Expanding the scope of DNA repair targeted therapies is essential for broader patient benefit.
  • Continued research into synthetic lethality holds promise for future cancer treatments.

Nucleotide Excision Repair

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...

DNA Damage can Stall the Cell Cycle

In response to DNA damage, cells can pause the cell cycle to assess and repair the breaks. However, the cell must check the DNA at certain critical stages during the cell cycle. If the cell cycle pauses before DNA replication, the cells will contain twice the amount of DNA. On the other hand, if cells arrest after DNA replication but before mitosis, they will contain four times the normal amount of DNA. With a host of specialized proteins at their disposal,cells must use the right protein at...

Overview of DNA Repair02:25

Overview of DNA Repair

In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage.

Long-patch Base Excision Repair

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:

Base Excision Repair01:54

Base Excision Repair

One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.

Mismatch Repair01:20

Mismatch Repair

Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
